About the SUTEハブ PCB

SUTEハブ is an open source STM32 PCB design by TOBA-Robocon, published on GitHub. It is a 2-layer board measuring 80 × 80 mm, with 62 components from 33 distinct parts.

Its main chip is the STM32F405RGTx, from the STM32 family. Other key parts include the NCS214, Regulator_5.0, Regulator_3.3, NJM7812 and CH340E. By type, the board carries 22 capacitors, 13 connectors, 13 resistors, 8 ICs, 2 switches and 2 LEDs.

From the project

鳥羽商船Aチームが2025年度のNHK高専ロボコンで使用した基板(公開用に多少編集済み)

付属のXT60に給電することで分岐先のUSB-Cの電源ラインに電源を供給できる。

電源を供給することで後述する「偽C610(C810)」を駆動させることができる。

本番で使った基板にはれな子のシルクが乗っているため、部内では「れな子」と呼ばれていた。

ESP32とF405RGTがついている。Dualshock4の値をESP32で受け取ってCANバスに流し散らかす。

Dualshock4の値を使って各機構の処理をし、4本のUSB-C_CANで各基板にデータを転送する。

SUTEハブ design files

The KiCad project lives in the TOBA-Robocon/NHK_2025_circuit_public_var repository on GitHub; these links point at the commit this page was built from.

SUTEハブ: common questions

What microcontroller does the SUTEハブ use?

The SUTEハブ is built around the STM32F405RGTx, from the STM32 family.

How big is the SUTEハブ PCB?

The SUTEハブ measures 80 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SUTEハブ?

62 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the SUTEハブ design files?

From the TOBA-Robocon/NHK_2025_circuit_public_var repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SUTEハブ design in my own project?

The repository has no license, so all rights stay with TOBA-Robocon. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the SUTEハブ without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
